Abstract

Achieving high pasture yields is essential for maintaining feed levels in cattle herds. Plant height and stem diameter are determinants of pasture production success by the amount of mass produced. One of the factors that change these rates is irregular rainfall, making it necessary to replenish demand through irrigation. The objective of this work was to evaluate stem diameter and plant height under different water conditions and forage sorghum cuts in two agricultural years in the state of Rio Grande do Sul. Two experiments were conducted in 2015/2016 and 2016/2017 in Santa Maria / RS, and plant heights and stem diameters were evaluated in six water conditions (non-irrigated, 25, 50, 75, 100 and 125% of ETo), in four replications, in three cutting periods (50, 80 and 110 days after sowing) in a randomized block design. Statistically significant differences were found for plant height and stem diameter variation, both according to irrigation depth and cut sequence.
